Product details
Overview
STEVAL-MKI089V1 from STMicroelectronics is an adapter board for the LIS331DLH 3-axis digital accelerometer, providing full pin access via a standard DIL-24 socket. It integrates decoupling capacitors (10 µF + 100 nF) on VDD, supports I²C/SPI communication, and is designed for rapid prototyping of motion-sensing applications in industrial and consumer systems.
For engineers reviewing the STEVAL-MKI089V1 datasheet, STEVAL-MKI089V1 pinout, STEVAL-MKI089V1 application, or STEVAL-MKI089V1 equivalent, this board enables direct evaluation of the LIS331DLH sensor with plug-and-play compatibility to the STEVAL-MKI109V2 motherboard and Unico GUI software stack.
Technical Context
The board maps all 24 pins of the LIS331DLH-including SCL/SDA for I²C, CS/SDO for SPI, INT1/INT2 interrupt outputs, and dual GND/VDD supply terminals-onto a DIL-24 footprint. No level-shifting or signal conditioning circuitry is integrated; it serves strictly as a mechanical and electrical breakout interface.
It requires external host control via the STEVAL-MKI109V2 motherboard, which provides USB-to-SPI/I²C bridging using a 32-bit STM32 microcontroller. The adapter itself contains no active components beyond passive decoupling capacitance and zero-ohm jumper R1 for Vdd_IO configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| DIL Socket Type | Standard 24-pin dual in-line socket, enabling direct insertion of LIS331DLH without soldering. |
| Power Decoupling | 10 µF tantalum + 100 nF ceramic capacitor on VDD line, meeting LIS331DLH supply stability requirements. |
| Interface Support | Full pin access for both I²C (SCL/SDA) and SPI (CS/SDO) protocols per LIS331DLH datasheet. |
| Interrupt Outputs | Dedicated through-hole pads for INT1 and INT2 signals, supporting configurable motion detection events. |
| Compatibility | Designed exclusively for use with STEVAL-MKI109V2 motherboard; no standalone operation capability. |
| RoHS Compliance | Fully compliant per EU Directive 2011/65/EU, verified in original ST documentation. |

FAQ
Does STEVAL-MKI089V1 include the LIS331DLH sensor?
No. The board is a passive adapter only-it provides the socket and routing for the LIS331DLH but does not include the sensor IC. Users must supply their own LIS331DLH device and mount it into the DIL-24 socket before use.
Can STEVAL-MKI089V1 operate independently without STEVAL-MKI109V2?
No. It lacks power regulation, microcontroller, USB interface, or firmware. It functions solely as a breakout interface and requires connection to the STEVAL-MKI109V2 motherboard to communicate with a PC or host system.
What software tools support STEVAL-MKI089V1?
ST's Unico GUI is the primary supported tool, downloadable from ST's official website. It communicates via the STEVAL-MKI109V2 bridge to configure LIS331DLH registers, stream real-time acceleration data, and generate custom firmware routines.
Is there a schematic or layout file available for STEVAL-MKI089V1?
Yes. The official schematic is published in DocID17454 Rev 2 (page 2), showing all passive components, header assignments, and LIS331DLH pin mapping. Gerber files are not included in the public data brief but may be requested directly from ST support channels.
